Subject: [PATCH] trace: fix SKIP_STACK_VALIDATION=1 build
Date: Fri,  8 Jun 2018 14:47:46 -0700	[thread overview]
Message-ID: <20180608214746.136554-1-gthelen@google.com> (raw)

Non gcc-5 builds with CONFIG_STACK_VALIDATION=y and
SKIP_STACK_VALIDATION=1 fail.
Example output:
  /bin/sh: init/.tmp_main.o: Permission denied

commit 96f60dfa5819 ("trace: Use -mcount-record for dynamic ftrace"),
added a mismatched endif.  This causes cmd_objtool to get mistakenly
set.

Relocate endif to balance the newly added -record-mcount check.

Fixes: 96f60dfa5819 ("trace: Use -mcount-record for dynamic ftrace")
